T0 A LL wHoM IT MAY CQNCERN:

Beit known that I, CHARLES F. HARrwIG, of West Haven,'n the county of-New Haven, and State of Con. nocticut, have invented a; new Improvement in Hose-Coupling; andd'do hereby declare'thc following, when tekcnin connection with theA accompanying drawings, andthe letters of Areference marked thereon, to be n full, clear, and exact description of the same,-a'nd which said drawings eonstitutepart of this`spec'ication',l and represent, in

Figure 1, a side view.

Figure 2, an end view otone part. Figure V3, an end view of the other part andV in Figure 4, e. longitudinal section of the Whole. p This invention lrelates to an improvement in coupling for connecting lengths ofhp'se, or for similar-purposes. To enable others to construct this improvement, I will proceed to described .the same, as illustrated in the accompanying drawings. A n l v A, is the one part, and B'the other part, to each of which one end of thelength of hose or thing to be coupled is attached. Around the part 4B is formed a flange,- C, anda ncck,'D, projecting inward from the lsaid ange, as seen in iig. 4, and on the said neck are formed 'two ormore lips, a, as seen in iigs.'3 4, the

said lips being'less in length than the space between. Upon the inner endof the part A is formada tiange, d,

Vand backl of the vsaid ilange a screw-thread is cnt, as denoted in ignfli,A and over the thread thus out is placed a ring, E, having a corresponding thread, so. tht-the said ringfmay be ireelyrturnledA to 6r fronithe ange d. The ring E has an internal annular groove, e, and into the groove Vare cn't, notches, F', corresponding in position to the lips a, as seen in g.,2, and so to admit of` thesaid lips passing freely into the groove e, asseen in iig. 4, and when so passed into the groove, may he'turned to the'right or left, so as to hold the part B within the ring E. On tothe partA issecurely and rmly-xcd a ring, Gpllavinga ange, H, projecting over the ring.E,. as seen in fig.'4, and, yet not soV as to interfere with the movement of the ring E, and the ring Grl is pro; vided with holesf, or other means vfor trningfthe partA A.4 Within the ring E, and on to the flanged, is'placed a packing, b, ofhrubber or other suitable material.v ".lhepa`rt B is ineerted within the ring as before',describedV and shown in ig."4; then, holding the part- B,'thc part A is'turned into t-hel ring E, the ring Ebein'g held stationary within the part B untilvthe flange d, on the part A, bears lhard'ar'gainst the end D of the partgB, the packing being between, vand thus th two parts are-firmly' secured together, and lthejoint tightly. packed.v

To separate the parts, reverse the m'ovement'of thel part A, to draw it backfroui the end of the part B,

i then the ring E may be'easily'turned 'to permit the part A' to be removed therefrom. VThe flange H protects the screw from being obstructed by4 sand or any foreign substance.

It will be seen that but a partial turn ofthe part A` will ble sufficient to relieve .the part B,Yso that thering E may be turnedto separate the two parts. lhns'-I/l1ave produced a coupling which may be adjusted very quickly, and Verycheap and simple initsconstruction.

I do not wish to be understood as broadly claiming the arrangement of the fiange H, so as 'to prevent tho admission ofsand to the screw.

Having, therefore, thus fully describedmyvinvcntion, what I claim as new and useful, and dcsireto securc by Letters` Patent, isl i The arrangement` of the ring G, provided with its ango H, upon the part A, in combination with the ring` E', constructed so es to operatefsuhstantially as set forth.
